Effect of Web-based Nursing Navigator Programme on Breast Cancer Screening Behaviors in Women at High Risk of Breast Cancer

Breast cancer is a very important health problem affecting women's health in the world and in our country. It was reported that 685,000 people died of breast cancer in the world in 2020. The American Cancer Society estimates that approximately 310,720 new cases of invasive breast cancer will be detected in women in the United States in 2024, approximately 56,500 new cases of ductal carcinoma in situ (DCIS) will be detected, and approximately 42,250 women will die from breast cancer. In Turkey, breast cancer is the most common type of cancer in women and the cause of most deaths. In national reports for our country, it was reported that the frequency of breast cancer in women in 2018 was 48.6 per hundred thousand and the number of newly diagnosed patients in the same year was 22,500. Early diagnosis of breast cancer, which is a very important health problem in terms of women's health, reduces mortality and provides the opportunity for breast-conserving surgery. Today, the most effective approach in reducing mortality rates in breast cancer is early diagnosis/screening methods. Early diagnosis/screening methods aim to detect abnormal changes in women's breast tissue at an early stage. Breast self-examination (BSE), clinical breast examination (CBE) and mammography are widely recommended early diagnosis/screening methods for the early detection of breast cancer. In order to detect breast cancer at the earliest stage, it is recommended that women without symptoms in our country have a BSE every month starting at the age of 20, have a CBE once a year, and have a mammogram every 2 years between the ages of 40-69.It is recommended that women at high risk of breast cancer start breast cancer screening earlier and be monitored more frequently than women without symptoms. The American Cancer Society recommends that women at high risk of breast cancer have a mammogram every year after the age of 30.
